At a purchase price just under 1.0-times Aspen's $36 million in annual sales, Moog paid a small premium to its own 0.8 P/S ratio. However, Moog Components Group President Larry Ball explained that the company needed Aspen to fill "a product and technology gap for our existing customer base."

Financially, Moog says the purchase will be neutral to its 2013 earnings per share.
